STILL FOR PETROLEUM-OIL OR HYDROCARBON FL'UlDfS.

SPECIFCATON forming part of Letters Patent No. 739,757, dated September22, 1903.

Application filed October 9, 1902.

T all whom it may concern.:

Be it known that we, WATSON RYDER and JOHN A. QUALEY, citizens of theUnited States,residing in the city and county of Phila` delphia, Stateof Pennsylvania, have invented new and useful Improvements in Stills forPetroleum Oil or Hydrocarbon Fluids, of which the following is aspecification.

Our invention consists of novel means for ro distilliug petroleum-oil orhydrocarbon fluids; and it consists of a still embodying a retort having,a circuitous or zigzag passage therein whereby the products ofcombustion of the furnace of the still are caused to traverse said x5passage, and thus subject the oil or fluid to an extensive heatingaction and cause a thorough vaporization of the oil or Huid.

lt also consists of the novel construction of the dues for the productsof combustion and 2o the crown-sheets of the retort with which said duesare connected, whereby during the expansion of said iiues andcrown-sheets they remain connected and injury to the crownsheets by thethrust against the same of the z 5 said iiues is prevented.

Figure l represents a front view of a still embodying our invention.-Fig. 2 represents. acentra-l vertical longitudinal section thereof. Fig.3 represents a transverse vertical section ;o through the retortdetached from the furnace,

the fines thereof having been removed. Fig. L represents an enlargedsectional detail with a portion broken away, showing the conlmunicationbetween one of the passages T and the space at the rear of the retort.

Similar letters of reference indicate corresponding parts in thefigures. Referring to the drawings, A designates a still which consistsof the top B, the sides to O, the upturned or arched base forming thechannel D, the end crown-sheets E, and the Iiues F, the latter beingconnected with said crown-sheets.

The retort is contained within the furnace 4'5 G and subjected to theproducts of combustion thereof. Within the retort is the diaphragm H,which is connected with the crownsheets E and serves to divide theretort into separate chambers and also acts as a brace 5o for saidsheets.

sheets and the end of the furnace adjacentto the chimney or stack J isthe horizontal plate K, it being notedthat spaces L L' exist between thecrown-sheets and the adjacent ywalls of the furnace, and the plate Kforms a division between the upperand lower portions ot' the vspaces atthe discharge end of the furnace. A damper L2 is provided forcontrolling thepassage L3, leading from the space L at the rear andcommunicating with the lower portion ofthe stack.

M designates the pipe for supplying the ,retort with petroleum-oil orhydrocarbon fluid.

N designates the head of the retort, the saute having connectedtherewith the vaporconveying pipe P, which is attached to the condenserQ.

R designates valved pipes which lead from the base of the retort and areconnected with the condensers S. In order to admit hot air to theproducts of combustion, we employ the ducts vT T, which are connectedwith the base of the retort and extend longitudinally along the same tothe rear passage L, they being open in front, whereby air may enter thesame through the draft wheel or opening in the fuel-supply door of thefurnace, and so reach said passage and commingle with vthe products ofcombustion thereof and burn in said passages with any gases which haveescaped uncombined from the furnace. The front of the furnace above thefuel-supply door is lclosed by doors which when opened permit access tothe adjacent ends of the iiues F for purposes of cleansing and repairs.'

The operation is as follows: vThe retort is supplied with petroleum-oilor `hydrocarbon fluid, which fills said retort and surrounds the dues F.The products of combustion from the furnace G pass through the chamberD, formed by the upturned base of the retort, thus heating said base,and consequently the oil or iiuid in the lower portion of the retort.The products of combustion then pass into the space L at the chimney orstack side and then enter the iiues F in the lower chamber of theretort, after which they pass to the front space L and rise therein,reaching the iues Fin the upper chamber of the retort nace therefor, aseries of flues for the prod-y and pass therethrough. Then they reachthe upper portion of the space L and finally escape into the chimney orstack, it being seen that by the provision of the additional plate Kacircuitous or zigzag passage is provided for the products of combustion,thus subjecting the petroleum-oil or hydrocarbon fluid to a longheating-surface, th us most highly heating the oil or fluid andefectivelydistilling the same. The vapors of distillation, such askerosene or light oils, enter the said head N and pass into the pipe E,whence they are directed into the condenser Q and collected therefrom inany suitable manner.` The residuum, tarry matter, &o., will bedischarged into device R when the valves of the same are opened andafterward subjected to the condensers S, from which they may be directedto a place of collection. The crownsheets E are bent or deflectedinwardly, and

the flues F are curved in their longitudinal direction. Consequentlywhen said flues expand, owing to the intense heat to which theyl aresubjected, their ends press against the crown-sheets, and as the latterare somewhat resilient in their nature they yield or give, so as toretain the connection of the flues with said crown-sheets and preventsaid flues from breaking through the latter, owing to the thrust of saidfilles in their expansion, or otherwise fracturing said sheets.

Having thus described our invention, whatV we claim as new, and desireto secure by Letters Patent, is i l. A petroleum-still havinga retort, afuructs of combustion within said retort and a perforated divisionaldiaphragm within the retort between the series of flues.

2. A petroleum-still having a retort, avfurnace therefor, a series offlues for the prod-` ucts of combustion within said retort, a divisionalperforated diaphragm within the retort between the series of flues, anda divisionplate between the walls of the retort and furnace at thedischarge end of the latter.

3. A petroleum-still having a retort and a furnace therefor, said retorthaving a base with au elevated portion forming a passage for theproducts of combustion from said furnace under Vsaid retort, aperforated diaphragm above said elevated portion, and a division-plateextended beyond the crownsheet at the discharge end of the furnace.

4. A petroleum-still having a. retort, a furnace therefor, an air-ductleading from the atmosphere along said retort to the rear of thecombustion-chamber of the furnace, a rear passage at the end of theretort connected with said duct, a series of flues for the products ofcombustion within said retort, a perforated diaphragm within the retortbetween saidjflues, and a division-plate between the walls of the retortand the furnace at the discharge end of the latter.

5. In a petroleum-still, a furnace and a retort, the latter having aflue therein for the products of combustion, the same being connectedwith the crown-sheet of the retort which crown-sheet is adapted to yieldwith the expansion of said flue without becoming disconnected therefromor fracturing said flue, and air-ducts at the base of said retortconnecting with spaces at the rear of the retort between itsrearcrown-sheet and the adjacent end of the furnace.

6. In a petroleum-still, a furnace, a retort with crown-sheets deflectedinwardly, and flues in said retort for the products of combustioii fromsaid furnace, said flues being deflected in longitudinal direction andconnected with said crown-sheets.

7. In a petroleum-still, a furnace and a retort having a flue in thesame for the products of combustion from said furnace, said retorthaving crown-sheets of deflected form and connected by said flue.

8. In a petroleum-still, a furnace, a retort, and a flue in said retortfor the products of combustion from said furnace, said flue and thecrown-sheet of the retort with which said flue is connected being ofdeflected form.

9. In a petroleum-still, a furnace and a retort having end crown-sheetsdeflected inwardly and flues curved in their longitudinal direction withtheir ends connected to said crown-sheets.

10. In a petroleum-still, a furnace and a retort having end crown-sheetsdeflected inwardly and flues curved in their longitudinal direction withtheir ends connected to said crown-sheets, and a longitudinal diaphragmconnecting. the crown-sheets at their central deflected portions.

11. In a petroleum-still, a furnace and a retort having end crown-sheetsdeflected inwardly, flues curved in their longitudinal direction withtheir ends connected to said crown-sheets, the spaces between thecrownsheets and the adjacent walls of the furnace communicating withsaid flues and a horizontal division-plate connecting the rearcrownsheet with the end of the furnace and dividing the spacetherebetween.
